Ios 如何将JSON中的字典与领域一起使用？

创建用于codable和realm的数据模型。我被字典卡住了。据我所知，你不能将字典用于领域？如何解码以下JSON并将其与Realm可以接受的内容一起使用

JSON示例A

"platform": {
            "data": {
                "25": {
                    "id": 25,
                    "name": "3DO",
                    "alias": "3do"
                },
                "4944": {
                    "id": 4944,
                    "name": "Acorn Archimedes",
                    "alias": "acorn-archimedes"
                },
                "4954": {
                    "id": 4954,
                    "name": "Acorn Electron",
                    "alias": "acorn-electron"
                }
}

注意，键是变化的字符串，在可解码的形式中，我将其作为

结构示例A

"platform": {
            "data": {
                "25": {
                    "id": 25,
                    "name": "3DO",
                    "alias": "3do"
                },
                "4944": {
                    "id": 4944,
                    "name": "Acorn Archimedes",
                    "alias": "acorn-archimedes"
                },
                "4954": {
                    "id": 4954,
                    "name": "Acorn Electron",
                    "alias": "acorn-electron"
                }
}

struct PlatformData : Codable {

let data : [String: PlatformInformation]
}

RealmSwift不支持字典。看看@DoesData，答案是2015年的，已经过时了。您可以轻松地与Realm一起使用。您甚至可以使用创建对象。还支持对JSON进行编码和解码。但是：答案将取决于对象如何交互。换句话说，在示例A中，平台有数据，但子数据本身似乎是其他对象的列表。正确吗？@Jay正确，在字典中，它有一个ID号作为字符串作为键，然后是一个其他对象的列表作为值。如果我输入适当的ID字符串，我就可以访问底层对象

let realmObject=realmObject类（值：[“id”：242，“type”：“fanart”]）

然后将其添加到列表中

let myList=list

。列表与数组非常相似，其行为方式也类似。
